A novel 6-speed automatic transmission is designed using the lever analysis, which consists of 3 single planetary gear sets, 3 clutches, and 2 brakes. The novel 6-speed automatic transmission has the planetary gear ratio of 1.5 ~ 3.0 and overall gear ratio of more than 6. In order to investigate the novel 6-speed automatic transmission performance, a performance simulator is developed using AMEsim software. It is found from the simulation results that the novel 6-speed automatic transmission is able to provide improvement of the maximum acceleration by 6.8%, 0 -100㎞/h acceleration time by 10.7%, fuel economy for HWFET mode by 5.9% in comparison with 5-speed automatic transmission.
